  <h1 class="topictitle1">(Optional) Synchronizing Trap Configurations to an Oracle Host</h1>
  <div>
   <p>If you have configured SNMP trap notification on the management page and want the alarm information of an Oracle host to be reported to the trap server through SNMP, synchronize the trap configuration to the Oracle host by referring to this section.</p>
   <div class="section">
    <h4 class="sectiontitle">Context</h4>
    <p>For Oracle database protection, you need to enable the archive log mode. In this mode, you need to set the archive space. After database backup is performed using the <span>product</span>, archive logs are periodically deleted to release archive space. However, if the archive log space is full because backup jobs cannot be executed properly for a long time or due to other reasons, production services will be affected.</p>
    <p>ProtectAgent monitors whether the archive space usage of the Oracle host exceeds the threshold (80% by default). When detecting that the usage exceeds the threshold, ProtectAgent instructs users to handle the exception in a timely manner in either of the following ways to prevent impact on production services:</p>
    <ul>
     <li>By default, the alarm is reported to the <span>product</span>, and the <span>product</span> reports the alarm to the trap server (only when SNMP trap notification is configured).</li>
     <li>If the alarm cannot be reported to the <span>product</span> in a timely manner because the <span>product</span> is abnormal or the network between the <span>product</span> and the host is abnormal, the Oracle host reports the alarm to the trap server through SNMP. This section describes how to synchronize trap information to the Oracle host so that the trap server can receive the alarm reported by the Oracle host, indicating that the archive space usage exceeds the threshold.</li>
    </ul>
   </div>
   <div class="section">
    <h4 class="sectiontitle">Prerequisites</h4>
    <ul>
     <li>You have configured SNMP trap notification on the management page.</li>
     <li>The Oracle host has executed backup once. Otherwise, the alarm will not be reported even if the archive space usage exceeds the threshold after trap information is synchronized to the host.</li>
    </ul>
   </div>

     <li><span>Choose <span class="uicontrol"><b><span><strong>More</strong></span> &gt; <span><strong>Sync Trap Info</strong></span></b></span> in the row where the Oracle host is located.</span><p></p>

       <div class="notebody">
        <p>If trap information needs to be synchronized for multiple Oracle hosts, repeat this step.</p>
       </div>
      </div> <p></p></li>
    </ol>
   </div>
   <div class="section">
    <h4 class="sectiontitle">Related Operations</h4>
    <p>If SNMP authentication information or trap server information is modified on the management page, you need to synchronize the updates to the Oracle host. The procedure is the same as the <a href="#EN-US_TOPIC_0000001839268293__section12928594219">preceding procedure</a>.</p>
